WOODWARD 9905-795 Tachometer Module

The WOODWARD 9905-795 biases the speed of an off-line generator set so that the frequency and phase match those of another generator or the utility bus. Then it automatically issues a contact closure signal to close the circuit breaker between the two when frequency and phase are matched within limits for a specified match-up time. The WOODWARD 9905-795 is a phase-locked-loop synchronizer and strives for a perfect match of frequency and phase.

The WOODWARD 9905-795 Synchronizer with voltage matching generates additional raise and lower signals (relay contact closures) to the generator's voltage regulator. Voltages must match within the WOODWARD 9905-795's tolerance before breaker closure occurs. For single-unit synchronization, installation of one synchronizer on each generator allows each unit to be individually paralleled to the bus. For multipleunit synchronization, one synchronizer can synchronize up to seven paralleled generator units simultaneously to another bus.
